I found this video from the New York University Entrepreneurs Speaker Series. It is all about starting up a business, in this case a tech business, but many of the ideas could be adapted for all businesses including checking out if an invention idea might be feasible. The speaker Amit Klein talks about how some of big companies such as Zappos and SkillShare tested out their ideas. Enjoy!
